Subject: [edk2-devel] [PATCH v5 27/28] ArmVirtPkg: Delete Memory Protection PCDs
Date: Sun,  8 Oct 2023 17:07:39 -0700	[thread overview]
Message-ID: <20231009000742.1792-28-taylor.d.beebe@gmail.com> (raw)
In-Reply-To: <20231009000742.1792-1-taylor.d.beebe@gmail.com>

Now that the transition to use SetMemoryProtectionsLib and
GetMemoryProtectionsLib is complete, delete the memory protection PCDs
to avoid confusing the interface. All memory protection settings
will now be set and consumed via the libraries.
